pjoin

fury.data.pjoin(a, *p)

Join two or more pathname components, inserting ‘/’ as needed. If any component is an absolute path, all previous path components will be discarded. An empty last part will result in a path that ends with a separator.

read_viz_icons

fury.data.read_viz_icons(style='icomoon', fname='infinity.png')[source]

Read specific icon from specific style.

Parameters

  • style (str) – Current icon style. Default is icomoon.

  • fname (str) – Filename of icon. This should be found in folder HOME/.fury/style/. Default is infinity.png.

Returns

path – Complete path of icon.

Return type

str

check_sha

fury.data.fetcher.check_sha(filename, stored_sha256=None)[source]

Check the generated sha checksum.

Parameters

  • filename (str) – The path to the file whose checksum is to be compared

  • stored_sha256 (str, optional) – Used to verify the generated SHA checksum. Default: None, checking is skipped

copyfileobj

fury.data.fetcher.copyfileobj(fsrc, fdst, length=16384)[source]

copy data from file-like object fsrc to file-like object fdst

copyfileobj_withprogress

fury.data.fetcher.copyfileobj_withprogress(fsrc, fdst, total_length, length=16384)[source]

fetch_data

fury.data.fetcher.fetch_data(files, folder, data_size=None)[source]

Download files to folder and checks their sha checksums.

Parameters

  • files (dictionary) – For each file in files the value should be (url, sha). The file will be downloaded from url if the file does not already exist or if the file exists but the sha checksum does not match.

  • folder (str) – The directory where to save the file, the directory will be created if it does not already exist.

  • data_size (str, optional) – A string describing the size of the data (e.g. “91 MB”) to be logged to the screen. Default does not produce any information about data size.

Raises

FetcherError – Raises if the sha checksum of the file does not match the expected value. The downloaded file is not deleted when this error is raised.
